Description

Automatic centering steel wire grabbing and assembling mechanism and automatic nut production equipment Technical Field The invention relates to the technical field of bolt processing, in particular to an automatic centering steel wire grabbing and assembling mechanism and automatic nut production equipment. Background In the production of nuts of a specific type (such as special nuts for locking, anti-loosening or as connectors), it is often necessary to vertically insert a length of steel wire into a preformed hole in the side wall of the nut and rivet or bend it to form functional structures such as anti-loosening teeth, handles or connecting rods, this process (wire assembly) being a key step in the production of such nuts, the quality of which directly affects the final function and reliability of the nut. At present, the automatic assembly of the procedure mainly faces two technical difficulties, namely, how to stably and accurately grasp the slender and flexible steel wire, and how to overcome the tiny centering deviation caused by the straightness error of the steel wire, the repeated positioning error of equipment and the tiny thermal deformation or vibration when the steel wire is inserted into the tiny hole of the nut, so that the smooth and damage-free insertion is realized. In the prior art, the automatic assembly of the steel wire mainly adopts a high-rigidity mechanical arm or a linear module, is provided with a pneumatic or electric clamping jaw to grasp the steel wire, and then directly drives the steel wire to be inserted into a nut hole by means of extremely high positioning precision of equipment. However, in the continuous motion process of the mechanical arm and the linear module, fine positioning deviation may occur, and this may lead to dislocation of holes on the steel wire and the nut, so as to cause assembly failure, and the steel wire itself is continuously fed through the feeding machine, no matter in the conveying or storage process, natural fine bending deformation may occur, if in the assembly process, the steel wire is directly spliced, even if the positioning is accurate, the problem that the surface of the steel wire is scratched or cannot enter the holes and be directly bent due to fine deformation of the steel wire itself may occur.
